Summary: Urban flood risk assessment is crucial for urban disaster management. Traditionally, only the area itself is considered in the evaluation, but this study proposes a conceptual model that takes into account the risks caused by road inundation and subsequent traffic jams. Using Haidian Island as an example, the study demonstrates that considering triggered risks reduces the overall risk in the outer ring subregions. This novel approach provides insights for flood risk assessment.

Summary: The study aimed to simulate urban flood scenarios in Malaysia's urbanized catchments in response to the increasing frequency and intensity of floods driven by climate change and urbanization. By using the PCSWMM model for flood simulation of the Damansara catchment, an integrated hydrologic-hydraulic model was developed and validated. The research findings demonstrated the effectiveness of current drainage systems in reducing flood risk caused by drainage overflow compared to historic drainage systems.

Summary: This study established a quantitative flood resilience index (FRI) to assess the resilience of specific locations to flooding. Results showed that Low impact development (LID) can reduce inundation area and depth during short-duration rainfall events, but its effectiveness during longer-duration events is negligible. However, LID could enhance urban resilience to flooding by reducing the duration of flooding events and thereby enabling earlier recovery efforts.

Summary: Drainage facilities and Low Impact Development practices are effective measures to reduce urban flood risk. This study used machine learning models to investigate the influence of pumping stations and LID practices on urban flood susceptibility. The results show that increasing pumping capacity and LID area can reduce flood susceptibility, and optimal design of these measures can effectively mitigate flood risk.

Summary: Understanding the characteristics of urbanization under different flood protection levels is crucial for sustainable development in coastal flood-prone areas. The study found that urban land expansion in Chinese CFAs increased rapidly, particularly in areas with low flood protection levels, highlighting the need to pay special attention to coastal landscape changes to reduce flood risk.

Summary: This research work implements the gridded Flash Flood Guidance (FFG) method to predict and evaluate flash floods in Greece. The FFG system serves as an Early Warning System (EWS) for flash flood threats, especially in small ungauged basins. The study examines the system's lead time using the catastrophic flash flood event that occurred in Greece in November 2017. The sensitivity analysis shows that soil moisture conditions are the most crucial aspect of the system and can significantly affect the lead time. If the system had been operational during the studied event, a five-hour lead time warning could have been issued based on the forecasted rainfall.

Summary: Recent studies show that low impact development (LID) is effective in preventing urban flooding in urban catchments, but little research has been done on how the performance of urban drainage systems (UDS) changes at the spatial scale under the effectiveness of LID. This study evaluates the performance of UDS under different spatial placement strategies of LID and finds that the placement location of LID has a significant impact on UDS performance, with uniform placement strategy being the best. Furthermore, placing LID facilities near flooded locations maximizes flood reduction benefits and reduces the transfer of hydraulic load to other parts of UDS.

Summary: This study conducted flash flood susceptibility mapping in the Sungai Pinang catchment in Malaysia using four machine learning models and the Statistical Index. The results showed that the combination of genetic algorithm and fuzzy unordered rules induction algorithm performed the best in terms of accuracy. Furthermore, twelve key flood variables were selected for optimizing the development of flash flood susceptibility mapping.

Summary: This study proposes a method that combines flow transmission chain and generalized differential evolution to simulate low impact development practices. The method achieves low relative error and improved computational efficiency under different LID scenarios. Compared to other algorithms, the generalized differential evolution algorithm can find the most cost-effective solution. The LID layout obtained through this method saves costs while reducing storm water runoff, providing better environmental benefits.
